CutSizeGenie is a Shopify app for fashion and apparel e-commerce brands that unlocks revenue from out-of-stock sizes using virtual inventory and size mapping. It improves size availability on Shopify product pages without theme edits.

Alteration workflow: make virtual sizes operations-friendly.

Virtual inventory works only if ops has clarity. Here’s a clean, low-drama workflow for warehouses that fulfil neighbouring sizes using tailoring/cut-size.

The 5-step ops SOP (simple + scalable)

Step 1 — Identify a virtual line item
Ops identifies orders that contain virtual sizes using app logs / tags / internal view (as configured). Goal: no manual guessing.
Step 2 — Pick the source size (jump size)
Warehouse picks the mapped source size from inventory (example: customer ordered S, source is M). The mapping is deterministic and logged.
Step 3 — Alter / cut-size as per SOP
Follow your standard tailoring SOP (pattern rules, permissible adjustment limits, quality check). If a style is not feasible, disable mapping for that style/category.
Step 4 — Pack & ship normally
Ship under the normal Shopify fulfilment process. The customer experience remains standard: same PDP, same checkout, normal fulfilment status.
Step 5 — Track exceptions
Track exceptions (not feasible, damage, time delay, shortage) and refine: mappings, thresholds, and caps.

Best practices (keeps ops happy)

  • Start small: pilot on a limited set of hero SKUs.
  • Conservative guardrails: higher thresholds + lower caps initially.
  • Exclude complex categories: heavily embellished or non-alteration-friendly styles.
  • One owner: assign a single ops owner for mapping enablement decisions.
  • Daily review: monitor virtual orders + exceptions for first 7 days.

Use thresholds and caps to protect your warehouse while increasing size availability on PDP.
